A visual companion to the components of SOSNA is provided in Figure 7-12.

Figure 7-12.Overview of SOSNA architecture

We start at the blockchain layer , which provides the consensus framework to the network, along with the smart contract system for governance. Next is the messaging bus layer that serves as a two-way communication channel between the various components of the world computer and users in the network. This layer also exists on both sides, allowing the blockchain to communicate to the consumer-facing applications and the grid core to coordinate task execution. On the very top, we have a consumer application layer where buyers can access the network and post requests for services. The RegApp is an early example of consumer applications that buyers would interact with in the future. Eventually, the consumer layer would split into more verticals with features such as trusted runtime skipping the verification stages from users with a high reputation in the network. On the opposite end, at the very bottom we have the grid core. This is the heart of SONM where the fog cloud computing takes place. The grid is essentially a parallel implementation of several hundred master and slave modules. The slave modules run containers where services execute, and these services are connected to a locator. The locator runs on a public port accessible to the buyer through the consumer-apps layer .
